Application filed January 10, 1928. Serial No. "245,737:

This invention relates to new and useful improvements in window shades and more particularly to an attachment for governing the rotation of the when attached to the conventional type of spring roller willserve to govern the rotation of the roller when winding the shade suspending means thereon.

Anotherobjectof this invention is'to provide a device of the character described, which pendlng means.

Other objects and many of the attendant advantages will be readily appreciated as the inventionbecomes better understood from a consideration of the illustrative embodiments of the same and for which purpose such descri tive drawin s have been hereto a end-,

ed, wherein: Flg. 1 1s an elevation of a window and shade, having the invention attached thereto.-

Fig. 2 is a fragmentary-sectional view of the device. i

Fig. 3 is a tion.

Fig. 4 is a section on the plane of line 44 Fig. 2, looking in the direction indicated. Fig. 5 is an elevation of a further form of the invention.

Referring more in "detail to the drawings perspective view of this invenin which similar reference numerals desig-i nate corresponding parts throughout the several views. j p i It will be seen that the device comprlslng this invention is mounted around the conventional type of spring roller 6 and consists of the collars 7 over which tube8 is mounted and secured by clamps'9 in such a manner that collars 7 constitute ends for the tube 8.

One of the clamps 9 is provided with an arm 10 of resilient material, which arm is deflected to lie adjacent the window-moulding l1 and be secured theretoby a staple 12 of sufliciently greater width to permit endwise movement of the arm. 10 therein thereby allowing for the end play of the roller. A tongue 13 is punched outwardly from the tube supporting roller thereof. An objector this invention is to provide a device of the character described, which,

, ,ltand is retained in collars l8 rigidly clampedtoe roller o ,by

allow free unwinding of the shade sus- '8"intermediatethe ends thereof, in a manner i to constitute a fissure 14.

collar' lo is mounted around; thespring and caused to outstand 17. This collar 15 is positioned intermediate the ends of tube 8 in such a manner that the hook 16 lies in adjacent relation to the fissure such position by guide screws 19. a 1

In operation it will be seen that the tube 8 and collars 7 are held in fixed relation to the window-moulding 11 with the spring roller 6 extending therethrough. As the shade suspending meansis unwound from the roller.6 causing its rotation, the tight-fitting collar 15 also rotates with its such a directionthat the with the fissure 14, but pending means is being wound upon the roller 6 by a reverse motion of the latter, then the hook will engage in the fissure 14 in .a manner to hold the collar 15 rigid to the stationary tube 8, when the collar will frictionally steady the rotation of the roller and thereby serve as a governor.

It will be obvious from the foregoing description that this invention is a great im-] provement in controlling means for window shadesand while the preferred embodiments hook will not engage have been disclosed, yetit is to be understood- 1. In combination with a spring roller for window shades, a governorcomprising a tube attached hook 16 in when the shade susloosely mounted on said roller in spaced relation thereto, an arm extending from said tube a T having connection with the window moulding, a tongue punched outwardly from said tube intermediate its ends forming a fissure, a collar mounted on saidroller within said tube having frictional contact with said roller, a hook, and a spring connecting said hook with said collar forcing said hook outwardly,

whereby it will engage in the fissure when rotated in one direction.

2. In combination with a spring roller for Window shades, a governor comprising a tube 5 loosely mounted on said roller in spaced relation thereto, an arm extending from said tube having connection with the Window moulding, a tongue punched outwardly from said tube intermediate its ends forming a fissure, a collar mounted on said roller within said tube having frictional contact Withsaid roller, a hook, a spring connecting said hook With said collar forcing said hookoutwardly, whereby it will engage in the fissure when rotated in one direction, and guide-collars fixedly mounted on saidroller, adapted to retain said collar centrally of said tube. V In testimony whereof I afiix my signature.
